QED Laboratory Stuff
This is where we will store all
information related to experimental work.
Lab Principles - good laboratory practice
The Ten Laboratory Commandments
- Keep a comprehensive and comprehensible Lab Book How_to_keep_your_log_book.pdf
- Make sure the lab is in a better condition when you leave than when you enter.
- Don't leave the lab unattended at the wrong time
- Do not leave broken or 'not-working-properly' stuff lying around
- Fix it before it breaks
- Keep the lab tidy
- Record borrowed items in the lab borrow book
- Mobile phone number
- Do not use lab computers for internet surfing, watching TV, etc

- Contain spreadsheets for helium log
- Labview software to control our experiments
- If you are using a current pinput on a lockin, or a current preamplifier, beware of the DC input offset (typically 1-10mV). This page shows a graphic example of what might happen to your measurement if there is a DC offset in the SR830.
- Information on where to get low noise co-ax cables, and cables made up with BNC, MCX, SMA connectors etc.
- Information on the output (noise) of DC voltage sources such at the Keithly 2400, Yokogawas and SR830 with and without filters.
- Checklist for progress and parts used to upgrade the RF sample holders used in our qubit and quantum dot experiments.

KeithlySMU Do Not Use SMUs when on a fridge or He3
, other than to check gate leakage at the start of an experiment. They are horribly noisy, and kill quantum effects.
